These jaws should of which lever C a rod, D, may extend to and be course be made strong enough to stand the I00 connected with a crank-shaft, or crank formed strain to which they are necessarily subjected.

in a shaft, as indicated by dotted lines, Fig. 2, We prefer to arrange the lever mechanism and the engaging jaws so that one pair of jaws and its corresponding lever mechanism shall be at the upper part of the frame-work, and so that the lever mechanism shall move in a horizontal plane. Beneath this the next pair of engaging jaws are set in the machine, with its lever mechanism working in a horizontal plane below the. first set. In like manner a third pair of engaging jaws and its lever mechanism may be placed still lower in the frame work of the machine, and so on until the desired number of sets are secured in place. The first or upper pair of engagingjaws are placed just beneath the hopper or mouth of the machine, and these jaws are preferably set farther apart than the pair just beneath them. The jaws of the second pair may be farther from each othei than the ones just below, an

so on until the series is completed.

The lever mechanism for operating the several pairs of engaging jaws can operate byone shaft, as shown in Fig. 3; but it may be desirable to employ counter-shafts for giving greater speed to the lower pairs of jaws than would be required for the upper one,the speed being made to increase with each succeeding pair. The reason for this is apparent, inasmuch as the upper pair would simply break the stone or ore, which drops to the jaws below in a greater number of pieces, each of which must be crushed, requiring a more active operation, in order that there may be no clogging.

The arrangement of the shafting to which the lever mechanism for operating the several pairs of engaging jaws is connected (shown in Fig. 4) is very well adapted,whenconnectcd, as therein shown, with the other mechanism for operating such shafting, to produce the requisite speed for each pair of engaging jaws. In this figure the shafting which operates the lever mechanism is shown as being divided into sections B B B", separated from each other by bearings Z). In the upper section the rod D is shown as being connected to a fly-' wheel, D, which has its bearing upon a shaft passing through a brace, and having a pulleywheel connected to the other end thereof. The same arrangement is employed for each succeeding pair of engaging jaws, with the exception that the pulley upon the shafting to which the fly-wheel for each succeeding pair is secured is in each case smaller than the pulley which operates the fly-wheel next above it. These several pulleys may be belted, as shown,with other pulleys upon a shaft still farther away, which may be located in any convenient part of the machine; but the pulleys upon such shaft diminishin sizein inverse order from those which operate the several fly-wheels, or may be arranged according to the speed required for each pair of engaging jaws. The mechanism for operating each set of jaws may, however, be operated by an independent shaft of its own, if desired.

In crushing material which needs to be pulverized or reduced to a very fine degree of comminution, one or more pairs of rollers or cylinders, I I, of any desired diameters and lengths, and made of iron, steel, or other material sufficiently hard and strong for the purpose, may be placed in the machine beneath the crushing-jaws, as shown in the drawings, Figs. 1. and 3. These rollers may be operated by the gearing J, or by any other desired means.

Itis obvious that the machine may be constructed with but a single pair of engaging jaws, if it is intended simply to break stone into pieces of some magnitude; or it may have any number of pairs of engaging jaws, and the rollers may or may not be used, according to the requirements of the work to be performed.

The operation of the machine will readily be understood. The shaft B, when setin motion, actuates the arms of the levers E, which by their connect-ion with the elbow-levers F F cause them to spread or contract, so that their elbows actuate the lovers G G upon their fulcrums f f, and their extremities are thereby made to bear upon the jaws H H, which come in contact with and crush the material fed to the machine.

Inasmuch as we have already prepared an application for a patent in which we claim compound-lever mechanism, practically such as that which is here adapted to operate the engaging jaws, and as ordinary rollers have heretofore been used for pulverizing or comminuting different materials, we do not intend to claim herein the compound lever mechanism simply; but

\Vhat we do claim, and desire to secure by Letters Patent, is

1. In a machine for crushing ore, stone, &c., the lever E, fulcrumed on a shaft, and elbow-1e vers F F, connected therewith, and also united together by a knee or toggle joint, in combination with. working-levers G Gand engaging jaws H H,- such working-levers being adapted to move the engaging jaws toward each other, whereby they may be made to crush the material, substantially as described.

2. In a machine for crushing ore, stone, &c., a series of two or more pairs of engaging jaws,and working-levers G G, adapted to work each jaw of the several pairs, in combination with elbow-levers F F, united by a knee or togglejoint, and rocking lever E, fulerumed upon a shaft and connected with said elbowlevers, substantially as described.

8. A machine for crushing ore, stone, 850., provided with a series of two or more pairs of engaging jaws, compound-lever mechanism for operating the same, and means for giving to the levers which operate each pair of jaws succeeding the first more rapid action than is given to the levers which operate the preceding pair, whereby the several pairs of engaging jaws may be made to keep pace with each other in crushing the material to different degrees of comminution, substantially as described.

4. In a machine for crushing ore, stone, &c., shaft B, lever-arm O, secured thereto, rod D, connected with said arm, and crank or fiy- Wheel D, connected with said rod, in combi- 5 nation with rocking lever E, secured to the witnesses:
